Caltech’s “Deadlines and Forms” website claims that regular decisions will be released mid-March, but I was wondering if anyone had a better approximation based on release dates of previous years.
Ehhh 3/13? Idk 
I thought it might be a day around Pi day.
I remember mine coming out a few days before pi day (maybe around the 11th or 12th).
^^^ MIT’s is better though, because it actually is on Pi day. And this year, it’s on ultimate Pi day! 3/14/15 
It’s normally on the Saturday before Pi day. So, March 7 or March 14
Last year they did not release the Saturday before pi-day. Also, admissions offices seem to announce the official date 4-5 days before said date occurs, and we’re already four days from March 7. When I called, they said mid-March. I think we’ll get an official date around March 8 (or sooner, if we’re lucky).
